Astrobuilder

Astrobuilder is an AI-driven space management RPG set in the ever-changing Neon Galaxy. You can travel across more than 150 planets and interact with over 600 intelligent NPCs, each with an identity, long-term goals, memories and decision-making logic. Your choices in trade, conversation, alliances and betrayal can ripple through the galaxy and reshape it.

Choose your path

You can start as a rookie trader, buying low, selling high, running a shop and building trade routes. Grow into a branch manager or tycoon leading a Commerce Guild, expand a network of shops and compete for vital trade routes. You can instead join a Military Faction, rise through its ranks and take part in its governance and interstellar wars, or enter as a Free Person and pursue your own goals with customizable difficulty settings and open-ended rules.

Trade and build an empire

Supply, demand and prices are always shifting. NPC decisions, new trade routes, faction relationships, wars, disasters and social events continually change planetary economies. Find regional price differences, open shops, recruit managers and set business policies as you build a commercial empire.

Govern and fight

As a member of a Military Faction, you complete assignments and earn Merit and Influence to unlock higher positions, greater authority and new career abilities. You can take part in energy development, commercial expansion, security maintenance, military transport, personnel appointments, resource allocation and planetary governance. Rise to become a Governor or Consul, shape faction policies, and influence the balance of power through alliances, contracts and rebellions.

When war breaks out, assemble a fleet and fight interstellar battles. Deploy different types of warships and use military abilities to command the battlefield and decide a planet's fate.

Characters and Prophecies

The galaxy's 600+ NPCs have individual backgrounds, relationships, goals and motives. They observe markets, each other and you, and react to what they see. Wars, alliances, betrayals and revenge become memories in an interconnected web called Destiny Orbits, shaping characters' relationships, goals and future actions.

You can choose different conversational styles or speak using voice input. A conversation can change a relationship, inspire a new goal or set a character on a new course. Prophecies reveal signs of coming wars, disasters and market crashes. You can prepare by changing trade routes and faction relationships, or intervene in characters' choices in an attempt to break a Prophecy and alter the future.

Outposts and generations

You can explore mysterious wormholes and establish frontier outposts from scratch. Allocate the population, upgrade facilities and unlock technologies with limited resources and under time pressure, while random events and unknown crises disrupt plans and test your efforts to survive and expand.

You can also build a family, raise descendants and plan their development and long-term goals. The Life Planner lets you follow their progress as they form relationships and build lives of their own. What you build, and the friends and enemies you make, can continue to shape later generations.

Create and modify

The Gameplay Lab and standalone Mod Editor let you change planets, factions, characters, goods, prices, ships, relationships, Prophecies and the world's rules, then publish creations to the Steam Workshop. You can import custom character appearances and parts, share character and faction card packs, and use AI to generate character biographies, names and worldbuilding content. Created characters and worlds can develop on their own.
